［摘要］黄骅市天健湖文体公园体育中心屋盖钢结构由游泳馆屋盖钢结构、体育馆屋盖钢结构和连接走廊屋盖钢结构3部分构成，结构形式为弦支网架。介绍了屋盖钢结构的分缝及结构体系的选定过程，详细阐述了恒荷载、活荷载、风荷载等主要荷载作用的取值，并对屋盖钢结构静力、动力反应进行了分析。结果表明，在各种设计荷载作用下屋盖钢结构设计能够满足相关规范的要求。［关键词］天健湖文体公园; 空间钢结构; 弦支网架; 动力反应中图分类号：TU393.3 文献标识码：A 文章编号：1002-848X(2015)16-0022-04
Structural design on the space grid with suspend string of the roof of sports center in Tianjian Lake Cultural Park of Huanghua CityWang Danni1, Yu Jinghai1,2, Yan Xiangyu1,2, Han Juan1, Guo Hongyun1,3, Dou Yubin1(1 Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China; 2 Tianjin Steel Building Structure Engineering Center, Tianjin 300072, China; 3 School of Civil Engineering, Tianjin University, Tianjin 300072, China)Abstract: The steel structure of the roof of sports center in Tianjian Lake Cultural Park of Huanghua City consists of three parts, including the steel roof natatorium, the steel roof gymnasium and the steel roof of connecting corridor. The structural style is space grid with suspend string. The process of the structural system and setting principle of the gaps of the steel roof were introduced. The values of dead load, live load and wind load were elaborated. The static and dynamic structural responses were also analyzed. Results show that the design of the steel roof can satisfy the criterion demands under all design loads.Keywords: Tianjian Lake Cultural Park of Huanghua City; spatial steel structure; space grid with suspend string; dynamic response
